Specification of Letters Patent. Patented Dec, 2'7, 1921 Application filed August 11, 1919. Serial No. 316,667.

cago, in .the county of Cook and State of Illinois, have invented certain new and useful Improvements in Boosters, of which the following is a full, clear, and exact specification.

My invention relates to boosters. I

It has for its object to provide an improved booster especially adapted to use in connection with pumping liquid by fluid pressure, as for instance in air lift pumping or the like. A further object of my invention is to provide a booster of improved construction having improved and simplified mechanism adapted to improve the operationof separating the gas and liquid and propelling the latter from the booster, to enable the condition of the latter at any time to be readily determined from a point outside the booster casing, and to provide a simplified,

and more inexpensive booster structure which may be more readily manufactured. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.-

F or purposes of illustration, I have shown in the accompanying drawings one embodiment which my invention may assume in practice. I

In these drawings,- V Figure 1 is a vertical sectional view of a booster constructed in accordance with my invention, parts being broken awayto show details of construction. v

Fig. 2 is a transverse sectional view thereof on line 22 of Fig. 1.

Fig. 3 is a vertical sectional view of the valve and float mechanism on a line cor responding to the line 33 of Fig. .2.

Fig. 4 1s a detail view showing my improved construction equipped with a bottom discharge pipe. 7

In my improved construction it will be observed that I have shown a booster cas-' mixture to the booster; flanges 7 8 on the members 5 and 6 being clamped together and to the casing by means of screws 9. In the top 3 of the casing, I have also provided an aperture 10, herein coaxially disposed over the open end of the riser 5 and adapted to receive a plate ll attachedto the top of the casing by screws 12 and having an umbrella surface 13 formed on its under side and located a substantial distance above the end of the riser 5. Here it will also be observed that apart from the riser 5, and herein on the opposite side of the casing therefrom, I have also provided a downwardly extending web 14, attached to, and herein formed integral with, the topof the casing and cooperating with the side wall thereof to form a substantially cylindrical, closed, liquid discharge pipe or passage extending from the top of the casing to a point above the bottom thereof. Here it will also be noted that above thedischarge passage thus formed.

and herein coaxially disposed therewith, I have likewise provided an aperture 15 adapted to be closed at will by a plate 16 attached to the top of the casing by screws 17, andthat in the side wall of the casing 1, and adjacent the top of the discharge passage mentioned, I have provided another opening 18 adapted to be closed by the same plate and herein having a discharge pipe 19 clamped thereover by means of screws 20, the construction being such that the discharge pipe may be connected at will over either aperture 15, 18 and the remaining aperture may'then be closed by the plate 16.

Attention is here also directed to the fact that I have also provided an aperture 21 'in thebottom 2 of the casing, preferably coaxially disposed with respect to the discharge passage formed by the web 14, which not only facilitates coring during the casting operation, but, as shown in Fig. 4, is adapted to receive when desired an upstanding discharge receiving member or pipe 22 which extends upward into the discharge passage mentioned and may or may not, at will, be provided with suitable openings 23, adapted to permit the discharge of liquid therethrough to the discharge line. Thus it will be observed that I have provided by the construction shown, an alternative construction adapted to use when a discharge from the bottom of the booster casing is for any reason desired, the apertures 15 and 18 then preferably being closed by plates correspondplate.

ingtothe p1ate16,whi1eat othertimes the: w I v determined amountzsufliient'to act upon the surface of'the liquid' at the bottom of the aperture 21 is usually closed by;v a. similart In my improved construction, it will also: be observed that the top '3 of the casing is. apertured, as at24, at a point herein at oneside ofa plane passing through the, axes of the riser 5 and the discharge passageiormed by the web 14. Insertible within this aperture and carried on a plate'et normally dlbs ing the sameand attached 'towtlie top ofdthe" casing screws 26, is a float frame 27; here n comprising a pair of rods fixed to the plate at their upper ends and rigidly" connected at-their bottoms by'aw plate" 28 having anaXialaperture 29 thereinadapted to receive and rguide' the lower 'end ofafloat rod 30 adj ustably 'carryingadiving bell float 3 1' thereon at a point below the plate 25 and having'aspring pressed relief l'valve mechanism 32 of the type described and claimed in my cor-pending applicationSeri-al No. 11355386, filed December 6,- 1916, on its 1 upper end," controlling the connection be tween the interior ofithe casing and the discharge pipe 33; HereinitWill. -also be*ob served that the frame 27 is partially-1 in closed by a guard, herein inthe form ofha tubular member? 38 which is spaced apart- -at its opposite ends from the: plate 28 andTtop 3 of the casing, theconst-ruction beingsuchthat the'efi'ect of surgin uponth'e float;- andtherefore upon the va ve, is minimized; at the sameftirne that a battle in the bottom of the casing is rendered unnecessary and the wholejmechanism is made capableof ber ing removed a as a: unit "from I thetop of the booster casing:

In my improved construction it will also be observed that it is made possible to cheapen the entire construction by casting the booster casing and that the number of parts therein is reduced and all parts thereinare readily removable, the umbrella as well as the valve and float being removable as units through the top f the casing. These and other advantages of my improved construction will, however, be clearly apparent to those skilled in the art.

While I have in this application specifically described one embodiment which my invention may assume in practice, it will be understood that this form is used for illustrative purposes and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
